The invention relates to the technical field of agricultural planting, in particular to a chloranthus spicatus flower promoting and controlling method which comprises the following steps: S1, planting substrate treatment: selecting 3 parts of
humus soil, 5 parts of
field soil, 1.5 parts of sand, 1.5 parts of dried pond
sludge, 0.8 part of a compound
fertilizer and 0.7 part of
coal cake
slag to prepare culture soil, sequentially laying coarse pebbles, gravel and fine sand at the bottom of a planting pond from bottom to top, and then laying the culture soil on the fine sand; S2, chloranthus
plant treatment: during March to April, dividing 2-3 water sprouts on a stock
plant into a group, gathering the water sprouts together, slightly
carving and burying the water sprouts with soil with the buried depth of 4.5-5cm, waiting for 2 months, selecting internode branches,
cutting the selected internode branches from the stock
plant, soaking the roots of the internode branches with rooting water, mixing and stirring a sterilizing solution and deep soil to form
slurry, and smearing roots of the internode branches with the
slurry. By means of the method, the problems that at present, chloranthus is generally cultivated artificially, the
flowering time of the artificially-cultivated chloranthus is different, and the chloranthus cannot bloom according to use requirements can be effectively solved.
